I had a hard time bleeding my master cylinder and and getting all the air out but finally have solid pedal, but have now discovered that my brake light switch is not working

. I had silicone fluid in the system previously and have switched back to conventional fluid. I have since learned that silicone isn't too friendly to hydraulic brake switches and I assume that's why my quit working.

Here is my question:
Is it possible to replace it WITHOUT having to bleed again?? I'm trying to avoid the hassle of bleeding again. Would appreciate any and all feedback.
